Table 3.
Variables measured in response to different hormone treatments including toad length, weight, the number and percentage of spawning toads, the number of oocytes, percent fertilization, number of neurulas, percent neurulation, and total number of neurulas. Treatment 7* was administered two doses of progesterone 12 hrs apart. Data in the table are expressedas Means ± SE and ranges of spawning toads.
